I’m beginning to like the idea in this space — local first with a backup with your own tool. Recently, https://hyprnote.com was popular here on Hacker News and it is pretty good. They also do the same, works local-first but you can use your preferred tool too.

Totally agreed, huge fan of Hyprnote as well. We work on two slightly different problems, but a lot of our tech has overlap, and our missions especially overlap :)
